STOCK-TANK HEATER.

Application filed March e1, 1919.

To all whom it may concern:

Be it known that I, HARDY A. FRIEND, residing at nlbert Lea,'-1n the county of Freeborn and State of Minnesota, have invented new and useful Improvements in Stock- Tank Heaters, of which the following is a specification.- 1

trated in the Thisinvention relates to heaters, particu- 'larly to heaters for heating the water in drinking troughs for cattle, andhas for its object the provision of a tank heater adapted lo burn kerosene or other heavy oil as a fuel,

and which is so constructed that it will very quickly and efliciently heat the water within a tank whereby to prevent freezing of the same, the device being of course immersec within the tank. p I

Another object. is the provision of a tank heater in which the body portion has a single integral casting and which is providedwith a cold air inlet flue provided with means for regulating the supply of cold air necessary to support combustion.

Another object is the provision of tank heater of this character which will be very simple and inexpensive in manufacture, highly efiicient in use, durablein service,

- and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more iiilly described and claimed, and illusaccompanying drawings, in whicha 5 Figure 1 is a side elevation of my device.

Fig. 2 is a longitudinal sectional view therethrough.

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a cross sectional View on the line 4-4: of Fig. 2. c

F ig. 5 is an end elevation looking at the main shaft. V

Fig. 6 is a detail plan view of the air inlet controlling means at thetop of the cold Referring more particularly to the drawings, the numeral 10 designates the main or body portion of the device which is formed preferably as a single casting and which includes a vertically extending shaft portion 11 which is preferably rectangular in cross section and open at its upper end, which also includes one or more, in the present instance 7 Specificationof Letters Patent.

3, tubes 12, extending from and communieating with one side of the lower portion of the shaft 11. Attheir outer ends the tubes 12 have formed thereon a chest member 13 which is preferably of spherical form and from which extends a plurality of legs 14 assisting in holding the device in proper position. Formed upon. the upper portion of the chest 13 is a tubular member 15 upon which :is internally engaged a smoke stack 16 carrying at its upper end a ventilatorl'? for preventing down draft. Upon its exterior the tubular member 15 is provided with a plurality of longitudinal ribs 18 serving as reinforcements. The tubes 12 are here shown as cylindrical in shape though it will be understood that they may be of any other desired cross sectional configuration and that the number may vary as it is possible to use a single tube if found preferable. i

Formed upon one side of the vertical shaft 11 is a tubular member 19 which is preferably slightly spaced from the associated wall and which has its lower end widened, as shown at 20, and communicating with the interior of the shaft 11 at its bottom. At its upper end the member 19 is closed by a cover 21 having a central opening 22 through.

which the cold air may continually pass. This cover is also so arranged that it may be slid to one side, thus admitting more air. Disposed upon the bottom of the shaft member 11 is a shallow pan 23 which is filled preferably with asbestos though any other similar absorbent material which is also noncombustible, may be used. This absorbent material is adapted to be saturated with oil and ignited whereby to provide the heat.

Disposed upon and forming a closure for the open top ofthe shaft member 11 is a tank 24% serving as an oil reservoir and provided with a handle 25 and a filling neck 26. This tank is provided in its bottom with an outlet cock 27 disposed above a funnelshaped extension 28 upon the upper end of a feed pipe 29 which preferably extends through and is held in position by apertured lugs 30 and which has its lower end terminating above the pan 23. A suitable door 31 is provided at a convenient point in the shaft member 11 so that the operator may reach in to light the oil within the pan 23.

1n the use of the device it is placed in position immersed in the water within a tank to be heated, it being of course understood that the smoke pipe 16 and top of the shaft member 11 must be above the level of the water to prevent flooding of the fire. When the cock 27 is opened to a small extent, the oil within the reservoir tank 24 will pass slowly out into the pipe 29 from which it will drop onto the absorbent material in the pan 28. After a small amount of oil has been thus deposited in the pan 23 the operator may open the door 31 and apply a lighted match or taper to the absorbent material in the pan to ignite the oil. The rapidity of the feed of the oil onto the pan 23 may be governed entirely by proper manipulation of the cook 27. It is of course apparent that the heat generated by the burning oil will pass through the tubular members 12 into the chest 13 and eventually out through the smoke stack 16. The passage of the heat through the tubes 12 and chest 13 will result in heating of water in the tank in which the device is disposed.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply constructed and inexpensive device adapted for ready disposition within a tank whereby the water within the tank may be easily and quickly heated, means being provided for controlling the supply of fuel and conse quently the degree of heat and also for mg 1 ,azeeas referred embodiment of m invention it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangementof parts aswill not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim A device of the character described comprising a vertically extending shaft member provided at its lower end with alateral extension, a plurality of horizontally disposed tubes communicating at one end with said extension, a spherical chest communicating with the other ends of said tubes, a vertical tubular member connnunicating with the upper portion of said chest and adapted to conduct the products of combustion, said shaft member, said tubes, said chest, and said tubular member being formed as a single casting, a vertically disposed tubular flue communicating at'its lower end with the lower portion of said shaft member at its side opposite said extension, a tank seated upon and forming a closure for the top of said shaft, and a feed pipe extending vertically within said shaft member and adapted to receive fuel from said tank.

In testimony whereof I affix my signature.

HARDY A. FRIEND.
